What Is The Required Torque For Installating A Threadripper CPU?

A couple of days ago I put together a Ryzen 1950x Threadripper into an MSI X399 Carbon motherboard, GTX 1060 graphics card, Samsung 960 NVMe M.2 drive, Enermax Liqutech 360 mm cooler etc. Things worked well, the machine posted and I installed Windows ... things were good. Today, I get an Ad "Ready to Boot Event" on the board and no graphic display at all, no post or anything. I called AMD and the call was pretty brief. The fellow said, "reseat everything".
